| A fragmentation structure is provided with improved performance e.g., fragmentation, projectile generation, storage, and manufacturing. An embodiment can include an open fragmentation structure that can be separated into individual components that can include a structure body section with a compartment, a removable initiator or detonator, a top cap section having an aperture configured to accept the removable initiator or removable detonator, and an explosive. An exemplary explosive can be preassembled to fit within the structure without a need for pouring in an explosive. An exemplary structure or top cap of the structure can receive an embrittlement treatment increasing its fragmentation characteristics. An ability of the structure to be easily disassembled allows for safer storage and a longer shelf life. A design of an exemplary embodiment of the structure allows it to be used with a wide range of explosive materials in addition to many types of removable initiators or detonators. | ||||||

| High explosive coatings and inks suitable for use in micro-electronic initiators for micro-electro-mechanical mechanisms used as safe and arm devices, are prepared from coating compositions of crystalline energetic materials and applied using various methods. These methods include wiping and spraying, as well as, pressure applications using a syringe or the like, and application of thick film ink to write specified patterns on a selected surface. A volatile mobile phase may be added to the coating composition to partially dissolve the energetic material so that, upon evaporation of the mobile phase, the energetic material precipitates and adheres to the selected surface. | ||||||

| 148 | LIGHTWEIGHT CARTRIDGE CASE | US12137989 | 2008-06-12 | US20090314178A1 | 2009-12-24 | JOSEPH T. SOUTH |
| Disclosed is an ammunition cartridge case that includes a sleeve, a base fixedly attached to the sleeve and a fiber reinforced polymer composite annulus that is at least partially within the base. In certain embodiments, the sleeve and the base are formed partly or entirely from a metal, for example steel or stainless steel. The base has a central aperture that affords for the annulus ring to fit within. The annulus is dimensioned such that it fits securely within the central aperture of the base and has a center aperture wherein a primer can be located. The annulus ring contains a volume of composite fibers ranging from 10 to 90 volume percent. The annulus isolates the primer from the cartridge case and thereby prevents galvanic corrosion between the primer and case. In addition, a metallic foil can be present between the annulus and the cartridge case in order to assure proper securement of the annulus therewithin. | ||||||

| 151 | Hand-held primer loading tool | US09372450 | 1999-08-11 | US06260463B1 | 2001-07-17 | Jerry D. Brand; Steven J. Koch; Steven R. Shields; Ronald L. Smith |
| A hand-held tool for loading a primer into a primer socket of an ammunition cartridge case includes an elongate body with a holder for holding a cartridge case with its primer socket in a target position in a priming station. An elongate track on the tool longitudinally guides a rectilinear primer holding strip through the priming station. A reciprocating advancing member moves in advancing and retracting directions, and in its advancing direction engages the primer strip to sequentially align successive primers in the strip with the target position. A detent holds the primer strip against retraction when the advancing member moves in its retracting direction. A plunger is mounted for shifting longitudinally of the body into and away from the priming station to push a primer out of the primer strip into the primer socket of the cartridge. An elongate operator handle is connected to the body for movement relative thereto. Movement of the handle in one direction produces advancement of the primer strip to align a primer with the primer socket and shifting of the plunger out of the priming station. Movement of the handle in the opposite direction moves the plunger into the priming station followed by retraction of the advancing member. The cartridge case holder includes a pair of opposed, laterally spaced shiftable gripper members having arcuate gripping faces which are spring biased toward each other to hold the base of a cartridge case. | ||||||
| 152 | Controlled depth primer seating tool | US462454 | 1990-01-09 | US5025706A | 1991-06-25 | Kenneth E. Markle |
| A controlled depth primer seating tool and method for use thereof in firearm cartridge loading and reloading operations, which enables the accurate measured depth of seating of a primer within the primer pocket of a center fire cartridge case by accommodating both cartridge case plus primer variations so that the measured depth of primer seating provides for a slight pre-load compression of the anvil head of the primer against the explosive compound contained therein whereby firing pin impact energy is thus optimally expended in effecting consistency of primer ignition with a corresponding enhancement of consistent ballistic characteristics from cartridge-to-cartridge and consequent accuracy from round-to-round. | ||||||
| 153 | Apparatus for processing cartridge cases | US527712 | 1990-05-22 | US4984501A | 1991-01-15 | Johannes Roller |
| An apparatus for processing cartridge cases, particularly for distinguishing between different fuzing systems of cartridge cases for center fire cartridges, comprises sensing means, which are reciprocable along the longitudinal center line of the cartridge case from and to a predetermined initial position, and means which oppose a displacement of the sensing means from the initial position. Means may be provided for indicating a displacement of the sensing means from their initial position. The apparatus may constitute a cartridge case processing tool for use in a machine for loading cartridge cases for center fire cartridges or may be integrated in the sizing die of such machine. The sensing means may comprise mechanical sensing means or an optical sensor, which is adapted to be inserted into the cartridge case and is opertively connected to an indicator. | ||||||

| A handloader tool for use in the fabrication of cartridge shells. The tool accomplishes uniform flash hole sizing. The tool includes a depth gage section which results in a cutting tool being inserted to a constant uniform depth into the cartridge flash hole. The cutting tool has an angled upper portion to provide a uniform chamfer of, for example, 60 degrees at the flash hole exit area.The overall tool assembly further includes a slidable centering cone to provide means wherein the cutting tool is always inserted at a desired straight angle into the flash hole area.The invention further includes a method of flash hole uniforming using the described handloader tool. | ||||||
| 155 | Primer pocket swaging device | US939069 | 1986-12-08 | US4732073A | 1988-03-22 | Douglas C. Semon |
| A primer pocket swaging device for use in cartridge reloading equipment, which is characterized by a cylindrically-shaped collet cover having a hollow, threaded interior for receiving a threaded nipple to enclose an expandable collet. The collet includes four shaped collet segments fitted together in expandable relationship by means of an O-ring and one end of a punch rod projects through the collet and the opposite end seats on the plunger of the reloading equipment by operation of a rod lock nut and an adaptor. The upper end of the collet cover is bevelled and fitted with an opening to receive the base end of an empty shell casing, wherein the base of the shell casing is inserted in the opening and is momentarily seated and held in the collet, while the punch rod extends upwardly and swages the empty primer pocket in the casing base responsive to operation of the reloading apparatus. After the swaging operation is complete, the casing is released from the collet by further manipulation of the reloading apparatus to force the punch rod downwardly and the primer pocket swaging device is in position to receive a second shell casing. | ||||||
